In the land of China and the vast China, monsters are everywhere. Onmyoji masters hold up the barrier. Within the barrier, monsters are not allowed to use magic within the barrier. Therefore, Xia Zimu, a descendant of the Onmyoji, holds a scroll of mountains and seas, which can allow monsters to attack. The scroll made an oath from heaven and earth not to harm human beings before they can perform magic. Monsters, like people, also have tears, cry and laugh. Since then, Xia Zimu has experienced the emotional entanglements of many monsters such as living souls, twin flowers, and mirror monsters.
